SASH-HOLDER.

SPECIFICATION forming part of Letters Patent No. 372,827, dated November 8, 1887.

Application filed April 5, 1887. Serial No. 233,766. (No model.)

To all whom it may concern:

Be it known that 1, ROBERT L. STOPFER, a

-citizen of the United States, residing at Philadelphia,in the county of Philadelphia and State of Pennsylvania, have invented certain new and'useful Improvements in Sash-Fasteners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and us'e-thesame, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to devices for fastening or looking sashes, and has for its object the provision of a simple and inexpensive'device which will combine the capacities for holding the sash at any height and looking it against being raised or lowered, as may be desired, and which at the same time will tighten the sash in the frame and prevent rattling, and consequently more thoroughly seal it against the passage of cold air. The device by which I accomplish this double function consists, essentially, of a button, which is pivoted to one of the side stiles of a windowsash in such position as to cause its wedge-shaped edge to enter the joint between the sash-stile and the window frame or strip when properly turned. The preferred form of button is ovate or approximately circular, with sloping front face all round, extending from a raised center to a thin edge, except where the extension is provided for forminga passage for the pivot or screw on which it turns. I prefer to make the sloping faces corrugated or rough, so that they will bite into the wood of the frame or strip and more securely hold the sash. I also prefer to form the center in'the shape of a projecting ridge, which will constitute a thumbpiece for more readily seizing the fastener when it is to be shifted or turned on its pivot.

The following detailed description of my invention will more fully explain its nature and use.

The accompanying drawings illustrate what I consider the best means for carrying my invention into practice.

Figure 1 is a front elevation of a portion of a window sash and frame with my device applied to one side of the sash. Fig. 2 is an edge View of the device detached. Fig. 3 is a section on line x m, Fig. 2. p

Similar letters of reference indicate cone 5 sponding parts in all the figures.

A is a portion of a window-frame, and B is a portion of a sash fitted therein.

D is my fastener, which is pivoted upon a pivot or screw, 0, which is passed through an extension or portion, 61, of the fastener and secured in the sash. The fastener is thereby held in proper position on the sash for engaging between the sash and frame or strip A.

The fastener consists of a button or swinging device having thin edge (1 extending around the greater part of its circumference,

a raised center or thumb-piece, d and sloping face d extending from the raised center to the thin edge all round on a plane or curved 7o (dished) line. The sloping face is corrugated,

as shown, for the purpose to be described. The fastener is pivoted to the sash in a position to cause its gravity to hold it just along side of the frame or strip, as shown in Fig. 1, 7 so that it can be turned into either of the positions illustrated in dotted lines, Fig. 1, andfor a simple fastening to hold the sash at any height either way of turning it will do; but it is most reliable in its action when turned with its body facing in a direction opposite to the direction in which the sash is likely to be moved. For instance, if it is desired to lock the sash against being raised, the fastener would be turned into the position indicated by upper dotted outline, (shown at e,) while if it is desired to lock the sash against being lowered and against slipping down by its own weight, it will be turned into the position shown by dotted lines f.

The corrugations d" are a very material aid to the action of the wedge, as they bite into the wood of the frame or strip A and make a firm hold.

In addition to holding the sash at any height, 5 the fastener presses it tightly against the outside of the frame, thus preventing rattling and also sealing the window pretty effectually.

Having thus described my invention, what I In testimony whereof I affix my signature in presence of two witnesses.

ROBERT L. STOPFER.
